[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] A power supply heat dissipation mechanism that is easy to disassemble includes a power supply 2 installed in a chassis 1, a heat dissipation component 3 is arranged in the heat dissipation direction of the power supply 2, the heat dissipation component 3 has two ends, and limit strips 4 are arranged on the two ends of the heat dissipation component 3, two guide seats 5 are respectively arranged on the two opposite inner side walls of the chassis 1, and any guide seat 5 is provided with a limit slide 6 that is adapted to the limit strip 4, and the two limit strips 4 can be respectively inserted into the two limit slides 6; a locking mechanism is also arranged on the chassis 1, and the locking mechanism can fix the limit strip 4 in the limit slide 6.

[0026] Specifically, the locking mechanism includes a locking member, a pressing mechanism connected to the locking member, and a stop mechanism linked to the pressing mechanism. The pressing mechanism includes a sleeve 7, a return spring 8 sleeved on the sleeve 7, and a limit baffle 9 arranged in a guide seat 5. A first slideway adapted to the sleeve 7 is provided in one of the guide seats 5. One end of the first slideway is connected to the outside through a first through hole located on the chassis 1, and the other end is connected to the limit slide groove 6 through a second through hole 10; the limit baffle 9 divides the first slideway into two parts. ; An annular groove is opened on the outer wall of the sleeve 7 along its axial direction, and this section is penetrated by the limit partition 9; the reset spring 8 is located in the annular groove, one end of which is connected to the pressing end of the sleeve 7, and the other end is connected to the limit partition 9; the stopping mechanism is arranged in the guide seat 5, the driving end of which is fixedly connected to the sleeve 7, and the execution end of which is detachably connected to the locking member; when the sleeve 7 is pressed, the stopping mechanism is linked to separate the locking member from the stopping mechanism, and after the locking member is separated from the stopping mechanism, the locking member can fix the limit strip 4 in the limit slide groove 6.

[0027] from Figure 2 and Figure 3 From the perspective of , the limiting baffle 9 fixed in the guide seat 5 is always in the annular groove. The existence of the annular groove enables the limiting baffle 9 to control the displacement of the sleeve 7 in the first slideway within a certain range, so that the sleeve 7 cannot be separated from the first slideway.

[0028] Specifically, the locking member includes a limit rod 11 adapted to the second through hole 10, a locking spring 12 sleeved on the limit rod 11, a limit ring 13 arranged on the limit rod 11 and a countersunk hole 14 arranged on the corresponding limit strip 4. The limit rod 11 is inserted into the second through hole 10 after being passed through the sleeve 7; the limit ring 13 is located between the sleeve 7 and the second through hole 10, one end of the locking spring 12 is connected to the sleeve 7, and the other end is connected to the limit ring 13; the execution end of the stopping mechanism is detachably connected to the limit ring 13; after the limit ring 13 is detached from the stopping mechanism during the pressing process, the limit rod 11 can be extended into the countersunk hole 14.

[0029] Specifically, the stop mechanism includes a push rod 15 fixedly connected to the sleeve 7, a stop rod 16 slidably connected to the guide seat 5, and a compression spring 17. The guide seat 5 is provided with a second slideway and a third slideway. The central axis of the second slideway is parallel to the central axis of the first slideway, and the central axis of the third slideway is perpendicular to the central axis of the first slideway. The push rod 15 is slidably arranged in the second slideway; the stop rod 16 and the compression spring 17 are both arranged in the third slideway, and one end of the compression spring 17 is connected to the bottom of the third slideway. The first end of the stop rod 16 is connected to the bottom of the third slideway, and the other end is connected to the bottom end of the stop rod 16; a slide groove 18 is provided in the middle of the stop rod 16, and a first inclined surface is provided at the bottom of the slide groove 18, and a second inclined surface adapted to the first inclined surface is provided at the free end of the push rod 15. When the sleeve 7 is pressed, the stop rod 16 moves toward the bottom of the third slideway under the action of the push rod 15; the top end of the stop rod 16 extends into the first slideway, and a groove 19 adapted to the limiting ring 13 is provided at the top end of the stop rod 16, and the limiting ring 13 is engaged with the groove 19.

[0030] In some implementations of this embodiment, a first guide surface 20 is provided at the top of the stop rod 16, and the first guide surface 20 is arranged opposite to the slot 19; a second guide surface 21 adapted to the first guide surface 20 is provided on the side of the stop ring 13 close to the sleeve 7. Figure 2 and Figure 3 From the perspective of FIG. 1 , this structure makes it easier for the stop rod 16 to move downward under the action of the limit ring 13 when the limit rod 11 is pulled to the left and the limit ring 13 contacts the top of the stop rod 16 .

[0031] In order to facilitate the movement of the sleeve 7 to drive the push rod 15 to move, the end of the push rod 15 away from the stop rod 16 is connected to the sleeve 7 through the connecting rod 22. At the same time, a first avoidance groove 23 is provided in the guide seat 5 so that the connecting rod 22 can move in the first avoidance groove 23.

[0032] from Figure 2 and Figure 3 From the perspective of FIG. 1 , after the push rod 15 is inserted into the slide groove 18, if the push rod 15 continues to move to the right, the free end of the push rod 15 may extend out of the slide groove 18, and the inner side wall of the third slideway may affect the movement of the push rod 15. In order to solve this problem and make the push rod 15 move to the right without restriction, a second avoidance groove 24 connected to the third slideway is provided in the guide seat 5, and the free end of the push rod 15 can extend into the second avoidance groove 24.

[0033] In some implementations of this embodiment, a limiting plate 25 is provided at one end of any guide seat 5 , and when the heat dissipation assembly 3 abuts against the limiting plate 25 , the countersunk hole 14 and the second through hole 10 are coaxial.

[0034] In some implementations of this embodiment, the limiting strip 4 is a dovetail block structure, and the limiting slide groove 6 is a limiting groove structure adapted to the limiting strip 4. Figure 1 From the perspective of the embodiment, the limit strip 4 and the limit slot 19 adopt a dovetail structure, which can limit the vertical displacement of the heat dissipation component 3 and increase the stability of the installation. In other implementations of this embodiment, the limit strip 4 and the limit slot 19 can also adopt a T-slot structure to achieve the limiting function.

[0035] Working principle:

[0036] from Figure 2 and Figure 3 From the perspective of the locking mechanism, when the locking mechanism does not need to fix the heat dissipation assembly 3, the sleeve 7 abuts against the limiting partition 9 under the action of the return spring 8, and the limiting ring 13 is located on the left side of the stop rod 16 (that is, the clamping groove 19 is clamped with the limiting ring 13). When the sleeve 7 is not pressed, the limiting rod 11 cannot move to the right due to the obstruction of the clamping groove 19, so that the end of the limiting rod 11 close to the limiting slide groove 6 cannot extend into the limiting slide groove 6.

[0037] When in use, the heat dissipation component 3 is first installed in the chassis 1. After installation, the two limit strips 4 are respectively located in the two limit slide grooves 6, and the heat dissipation component 3 is abutted against the limit plate 25. At this time, the countersunk hole 14 and the second through hole 10 are coaxial.

[0038] When fixing the heat dissipation assembly 3, the sleeve 7 is pressed to move it to the right. During the rightward movement of the sleeve 7, the reset spring 8 and the locking spring 12 are compressed, and the push rod 15 is also moved to the right under the drive of the sleeve 7. During this process, the second inclined surface of the free end of the push rod 15 squeezes the first inclined surface at the bottom of the slide groove 18, and the stop rod 16 moves downward under the action of this squeezing force. During the downward movement of the stop rod 16, the contact area between the card groove 19 at the top and the limit ring 13 gradually decreases. When the card groove 19 is completely separated from the limit ring 13, the sleeve 7 is stopped from being pressed. At this time, the limit rod 11 moves to the right under the action of the elastic force of the locking spring 12, and one end of the limit rod 11 extends into the countersunk hole 14 on the limit strip 4. The limit rod 11 maintains this locking state under the action of the locking spring 12, and the limit rod 11 is about to fix the limit strip 4 in the limit slide groove 6, so that the heat dissipation assembly 3 cannot be removed from the chassis 1. When the clamping groove 19 is completely separated from the limiting ring 13 and the sleeve 7 is stopped from being pressed, the sleeve 7 moves to the left under the action of the return spring 8 until it abuts against the limiting partition 9. During this process, the push rod 15 also moves to the left, and the stop rod 16 moves upward under the action of the compression spring 17 until the entire locking mechanism is in a balanced state.

[0039] When the heat dissipation assembly 3 fixed in the chassis 1 needs to be removed, the limit rod 11 is pulled to the left, and the locking spring 12 is compressed during this process. During the leftward movement of the limit rod 11, the second guide surface 21 and the first guide surface 20 go through a process from non-contact, to contact, and then to separation. During the contact process between the second guide surface 21 and the first guide surface 20, there will be an extrusion force between the two, and this extrusion force causes the stop rod 16 to move downward during this process. When the second guide surface 21 and the first guide surface 20 are completely separated during the leftward movement of the limit rod 11, the stop rod 16 moves upward under the action of the compression spring 17 until the card slot 19 is engaged with the limit ring 13. Then stop pulling the limit rod 11, and at this time, the end of the limit rod 11 close to the limit slide 6 retreats into the second through hole 10, and at this time, the movement of the limit bar 4 in the limit slide 6 is not restricted by the limit rod 11, so that the heat dissipation assembly 3 can be removed.

It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
